Description

  The present invention relates to a housing for housing a substrate.

  Patent Literature 1 as a housing having the above configuration includes a first guide protrusion for positioning in a lateral direction which is the width direction of the substrate inside a case for housing the substrate, and an opening at an end of the case. A technology is described in which a vertical positioning portion is provided on an inner surface of a cover for closing the substrate from a vertical direction which is a thickness direction.

JP 2006-19674 A

  A vehicle having an internal combustion engine, such as an automobile, requires a substrate for controlling the internal combustion engine and devices provided on the vehicle body, and the substrate is provided in each part of the vehicle body in a state of being housed in a sealed case. Can be

  In a vehicle, the case may vibrate due to vibration during traveling. At this time, if the substrate is not properly held inside the case and there is a gap between the substrate and the member holding the substrate, the substrate vibrates inside the case and leads to generation of abnormal noise.

  Here, considering the configuration of Patent Literature 1, in this Patent Literature 1, a guide portion formed inside the case holds the front end to the middle in the insertion direction of the board, and a vertical positioning portion formed on the cover. To hold the rear end in the board insertion direction. However, in the configuration of Patent Literature 1, although the cover and the case are fixed, since there is no configuration for integrally fixing the substrate, the case, and the cover, there is a gap between the case and the cover. In such a case, when an external vibration acts, the substrate may vibrate due to the gap and generate abnormal noise.

  For these reasons, there is a need for a housing that can suppress vibration of the substrate even when external vibrations are applied.

  The characteristic configuration of the housing according to the present invention includes a case having an opening on one end side, and a cover for closing the opening, wherein a substrate is accommodated in the case, and the cover is closed in a state where the cover is closed. Has a pressing and holding portion that presses and holds the substrate against the case by applying a force to the substrate.

According to this characteristic configuration, in a state where the substrate is housed in the case and the opening of the case is closed with the cover, the pressing / holding portion applies a force to the substrate, and the substrate is pressed against and held by the case with the force. Further, in a state where the substrate is held in the case, the reaction force of the force acting on the substrate from the pressing and holding portion acts on the cover, so that it is possible to suppress the relative displacement between the substrate and the cover. On the other hand, the substrate is held. In the state where the substrate is held by the case and the cover in this manner, for example, even when vibration from the outside is transmitted to the substrate, the substrate does not relatively displace with respect to any of the case and the cover. Can also be suppressed.
Therefore, a housing that suppresses the vibration of the substrate for both the case that accommodates the substrate and the cover that closes the opening of the case and that does not generate abnormal noise is configured.

  As another configuration, the case includes a guide member having two guide surfaces whose upper surface side and lower surface side face each other to guide the substrate inserted through the opening along a guide path. And the pressing and holding unit is configured to include a pressing member that abuts on the substrate and applies a pressing force to press the substrate against one of the two guide surfaces. Is also good.

  According to this, by inserting the substrate between the two guide surfaces, the substrate can be inserted into the case along the guide path. In a state where the opening of the case is closed with the cover, the substrate is pressed against one of the two guide surfaces by a force acting from the pressing member, and the pressing state in which the substrate is sandwiched between the guide member and the pressing member is performed. Produced. Thus, the substrate can be held while being pressed against the guide body, and the vibration of the substrate can be suppressed.

  As another configuration, the pressing / holding portion abuts on the surface of the guide member on the side opposite to the guide surface against which the substrate is pressed by the pressing force from the pressing member, so that the pressing member acts from the pressing member. A regulating member for regulating displacement of the guide member due to pressure may be provided.

  According to this, in a state where the substrate is housed in the case and the opening of the case is closed by the cover, the substrate is pressed against one of the two guide surfaces by the pressing force from the pressing member, and the guide member against which the substrate is pressed in this way. The restricting member comes into contact with the surface opposite to the surface on which the substrate is pressed. Thus, the displacement of the guide member caused by the force applied from the pressing member can be received by the regulating member, and the posture of the guide member can be stabilized, the substrate can be held more favorably, and the vibration of the substrate can be suppressed.

  As another configuration, a protrusion that applies a pressing force in the same direction as the pressing force applied to the substrate by the pressing member by abutting on the distal end portion of the substrate in the direction of insertion into the case includes a protrusion. One of the two guide surfaces may be provided on the other one of the guide surfaces.

  According to this, when the substrate is accommodated in the case along the guide path, the protrusion comes into contact with the distal end in the insertion direction of the substrate, and the pressing force applied from the protrusion causes the substrate to be guided by the guide material. Press on the surface. Since the direction of action of the pressing force is the same as the direction in which the pressing force acts on the substrate from the pressing member, in a state where the opening of the case is closed with the cover, the distal end of the substrate in the inserting direction moves in the insertion direction. The substrate is pressed against the guide surface of the guide member in the region extending to the rear end, and no gap is formed between the substrate and the guide member. Thereby, the vibration of the substrate can be further suppressed.

As another configuration, a portion near the opening of the guide member having the other one of the two guide surfaces is removed, and the other one of the two guide surfaces is removed. The length of the guide member having the guide direction is shorter than the length of the guide member having one of the guide surfaces in the guide direction, whereby the length of the guide member having the other one of the guide surfaces is reduced. An open space is formed on the outer end side,
The pressing member may be accommodated in the open space.

  According to this, when the substrate is stored in the case and the opening of the case is closed by the cover, the pressing member is stored in the open space, and the pressing force from the pressing member thus stored can act on the substrate. It becomes possible. In particular, in this configuration, since the guide member and the pressing member can be arranged at overlapping positions when viewed in a direction perpendicular to the substrate surface, the substrate can be strongly pressed against the guide surface of the guide member. Further, since the substrate is sandwiched and held between the pressing member and the guide member, the relative positional relationship between the substrate, the case, and the cover is uniquely determined, so that the substrate can be held more favorably, and the vibration of the substrate can be reduced. Can be suppressed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Basic configuration)
As shown in FIGS. 1 to 3, a housing A includes a resin case 10 that accommodates the substrate 1 and a resin cover 20 that closes an opening 10 a of the case 10. The board 1 has a connector 3 on which the electronic component 2 is mounted and which is connected to a printed wiring so as to enable access to information on the mounted electronic component 2.

  The housing A is a housing that accommodates a board 1 that constitutes an ECU (Electronic Control Unit) that controls an engine in a vehicle such as an automobile. Information required for control is input by a cable connected to the connector 3. Is output. The housing A is supported by the body frame or the like in an arbitrary posture. The positional relationship between the components will be described based on the posture shown in FIG. In particular, the left-right relationship, the up-down relationship, and the anteroposterior relationship are shown in FIG.

〔Case〕
As shown in FIGS. 1 to 4, the case 10 is in the shape of a bottomed rectangular tube, and integrally forms an upper wall 11, a lower wall 12, left and right side walls 13, and a bottom wall 14 connected thereto. In addition, a rectangular opening 10 a is formed at a position facing the bottom wall 14. An engaging projection 15 for engaging and holding the cover 20 and a holding body 16 for holding a bracket (not shown) to the case 10 when supporting the housing A on the vehicle body are provided on the outer surface of the side wall 13. Are formed.

  As shown in FIG. 2 and FIG. 4, the inner surfaces of the left and right side walls 13 have a main guide member 31 in a rail shape for guiding the substrate 1 along the guide path, and a sub guide member 32 in a posture parallel to each other. Are formed respectively. The main guide member 31 and the sub guide member 32 are disposed at positions facing the upper surface side and the lower surface side of the substrate 1 along the guide path, respectively.

  As shown in FIGS. 6 and 7, a main guide surface 31 a is formed below the main guide member 31 (a surface facing the upper surface of the substrate 1), and is above the sub guide member 32 (a surface facing the lower surface of the substrate 1). Surface) is formed with a sub guide surface 32a. A guide path is formed between the main guide surface 31a and the sub guide surface 32a. The distance between the main guide surface 31a and the sub guide surface 32a is set to a value slightly larger than the thickness of the substrate 1.

  As shown in FIGS. 7 to 9, the length of the main guide member 31 in the guide direction is set so as to reach the vicinity of the opening 10 a from the bottom wall 14. The sub guide member 32 is formed in a shape in which a portion closer to the opening 10a is removed as compared with the main guide member 31. As a result, the length of the sub guide member 32 is shorter in the guide direction than the main guide member 31. Due to this length relationship, the sub guide member 32 is on the outer end side (the side close to the opening 10a) of the sub guide member 32, and An open space S is formed on the lower side.

  As shown in FIG. 7, when the board 1 is inserted into the case 10, the sub-guides are configured such that the protrusions 33 abutting on the lower surface of the leading end in the insertion direction of the board 1 project upward from the sub-guide member 32. It is formed integrally with the member 32. Specifically, a protrusion 33 of the sub-guide member 32 is formed to protrude upward from the sub-guide surface 32 a near the bottom wall 14. In this configuration, the distance between the protruding end (upper end in FIG. 7) of the projection 33 and the main guide surface 31 a is set slightly smaller than the thickness of the substrate 1. The protruding portion 33 is formed in a plate shape extending in the direction along the guide direction, and is formed such that the base end portion has a large plate thickness and the plate thickness (length in the left-right direction) decreases toward the protruding end.

  With such a configuration, the substrate 1 is inserted between the main guide member 31 and the sub guide member 32 as shown by a two-dot chain line, and when the substrate 1 reaches the insertion end as shown in FIG. When the upper end portion of the projection 33 is crushed by the substrate 1, the insertion of the substrate 1 is permitted, and the projection 33 is in strong contact with the lower surface of the substrate 1. As a result, a force acts on the substrate 1 in a direction of lifting upward, causing the upper surface of the substrate 1 to strongly contact the main guide surface 31a, and this pressed state is maintained.

〔cover〕
As shown in FIGS. 1 to 3, the cover 20 has a cover body 21 disposed at a position where the opening 10 a is closed, and a pair of right and left engagement members that engage with the engagement protrusions 15 on the outer surfaces of the left and right side walls 13 of the case 10. The mating connection member 22 is formed integrally.

  The cover body 21 has a hole 21a for exposing the outer end of the connector 3 provided on the substrate 1. The engagement connecting member 22 is configured to maintain the state of being engaged with the engagement protrusion 15 by the elastic force of the resin, and the engagement of the engagement protrusion 15 can be released by a manual operation.

  In particular, as shown in FIGS. 3, 5, 8, and 9, a pressing member 24 extending in the direction of the case 10 and a regulating member 25 are formed on inner surfaces of both ends of the cover 20 in the left-right direction. ing.

  The pressing member 24 is inserted into the case 10 from the opening 10 a of the case 10 with the cover 20 provided at a position to close the opening 10 a of the case 10, and is arranged at a position where it contacts the lower surface of the substrate 1. On the upper surface of the pressing member 24, a plate-shaped pressing portion 24a is provided to protrude upward. The pressing portion 24a is formed so that the plate thickness at the base end portion is large and the plate thickness (length in the left-right direction) becomes smaller toward the distal end side.

  The regulating member 25 is inserted into the case 10 from the opening 10 a of the case 10 with the cover 20 provided at a position to close the opening 10 a of the case 10, and is arranged at a position where it contacts the upper surface of the main guide member 31. And is integrally formed with the cover 20. On the lower surface of the regulating member 25, a flat regulating surface 25a is formed.

  In other words, the restricting member 25 contacts the upper surface of the main guide member 31 opposite to the main guide surface 31a with which the substrate 1 contacts in a pressed state, so that the main guide member 31 is pressed by the pressing force applied from the pressing member 24. Regulate upward displacement.

[Substrate holding form]
In the case A, the substrate 1 is accommodated in the case 10, and when an operation of closing the opening 10 a of the case 10 by the cover 20 is performed, a force associated with the closing operation is applied to the substrate 1 so that the substrate 1 is moved. Is held between the main guide member 31 and the pressing member 24 and, at the same time, the main guide member 31 is pressed by the regulating member 25 to hold the substrate 1 on the case 10.

  That is, the pressing and holding unit H has the pressing member 24, the regulating member 25, and the main guide member 31, and when the pressing member 24 is pressed against the lower surface of the substrate 1, the pressing member 24 and the substrate 1 Relative movement becomes impossible, and the substrate 1 is held on the cover 20 via the pressing member 24.

  As described above, since the distance between the protruding end of the protrusion 33 and the main guide surface 31a is set smaller than the thickness of the substrate 1, the substrate 1 is moved to the main guide member 31 as shown in FIGS. When inserted along the guide path between the sub guide member 32 and the sub guide member 32, in the process in which the leading end in the insertion direction of the substrate 1 reaches a position where it contacts the inner surface of the bottom wall 14, The lower surface of the tip portion comes into strong contact with the projection 33, and the projection end of the projection 33 is crushed.

  Thus, when the distal end of the substrate 1 in the insertion direction reaches a position where it comes into contact with the inner surface of the bottom wall 14, the crushed portion of the protrusion 33 applies pressure to the lower surface of the distal end of the substrate 1 in the insertion direction. In order to act, the tip of the board 1 in the insertion direction is continuously pressed against the main guide surface 31 a of the main guide member 31.

  With the substrate 1 housed in the case 10 in this manner, the cover 20 is set at a position where the opening 10 a of the case 10 is closed, and the two engagement connecting members 22 are engaged with the corresponding engagement protrusions 15. The cover 20 is held by the case 10. In this state, as shown in FIG. 9, the pressing member 24 is housed in the open space S below the main guide member 31 on the outer end side of the sub guide member 32.

  When the cover 20 is engaged with the case 10, the upper end portion of the pressing portion 24 a of the pressing member 24 makes strong contact with the lower surface of the substrate 1. Due to such strong contact, a part of the upper end portion of the pressing portion 24a is crushed, and the rear end portion of the substrate 1 in the insertion direction is continuously pressed against the main guide surface 31a of the main guide member 31. become.

  Further, when the pressing portion 24a of the pressing member 24 comes into contact with the lower surface of the substrate 1, the restricting surface 25a of the restricting member 25 functioning as the pressing and holding portion H is positioned on the upper surface of the main guide member 31 (the side opposite to the main guide surface 31a). Surface). By the contact of the regulating surface 25a as described above, the regulating member 25 receives the force acting on the main guide member 31 from the pressing member 24 and regulates the upward displacement of the main guide member 31. Can be held in position.

  As shown in FIG. 6, in a state where the cover 20 is provided at a position where the opening 10 a of the case 10 is closed, the pressing member 24 and the regulating member 25 are arranged at positions vertically opposed to each other across the substrate 1. Therefore, the force transmitted from the pressing member 24 to the main guide member 31 via the substrate 1 can be received without difficulty by the restricting member 25, and the biased force does not act on the substrate 1, the main guide member 31, and the like. .

[Operation and effect of the embodiment]
As described above, in the housing A, the substrate 1 is housed inside the case 10, and the operation of closing the opening 10 a of the case 10 with the cover 20 is performed. 24, the substrate 1 is sandwiched, and the protruding portion 33 further presses the distal end of the substrate 1 in the insertion direction against the main guide surface 31a. As a result, the state where the region from the front end to the rear end in the insertion direction of the substrate 1 is pressed against the main guide surface 31a of the main guide member 31 is maintained, so that the substrate 1 is held against the case 10. Become. At the same time, the substrate 1 is held by the cover 20 so that the pressing member 24 keeps pressing the substrate 1.

  Thus, even in a situation where vibration from the outside is transmitted, the substrate 1 does not vibrate with respect to both the case 10 and the cover 20, and no abnormal noise is generated.

  Furthermore, when the substrate 1 is accommodated in the case 10 and the opening 10 a of the case 10 is closed with the cover 20, the main guide surface 31 a of the main guide member 31 against which the substrate 1 is pressed by the pressing force of the pressing member 24. The restricting surface 25a of the restricting member 25 comes into contact with the surface on the opposite side of the restricting member 25. Accordingly, the displacement of the main guide member 31 due to the force applied from the pressing member 24 is received by the regulating member 25, and the substrate 1 can be held at an appropriate position via the main guide member 31.

  When the operation of closing the opening 10a of the case 10 with the cover 20 is performed, the pressing member 24 is accommodated in the open space S, and the position where the main guide member 31 and the pressing member 24 overlap in a direction orthogonal to the substrate surface. The substrate can be strongly pressed against the guide surface of the guide member.

[Another embodiment]
The present invention may be configured as follows in addition to the above-described embodiment (those having the same functions as those of the embodiment are denoted by the same reference numerals and symbols as those of the embodiment).

(A) As shown in FIGS. 10 and 11, the contact portion 25 b that contacts the inner surface of the upper wall 11 of the case 10 with respect to the regulating member 25 (an example of a pressing holding portion) is located on the opposite side of the regulating surface 25 a. Form. That is, when the cover 20 is at the position where the opening 10a of the case 10 is closed, the regulating surface 25a of the regulating member 25 contacts the upper surface of the main guide member 31 (to the surface opposite to the main guide surface 31a), The contact portion 25 b of the regulating member 25 is configured to contact the inner surface of the upper wall 11 of the case 10.

  The regulating member 25 functions to regulate the phenomenon that the main guide member 31 is displaced by the force acting from the pressing member 24, but the reaction member 25 is moved upward from the main guide member 31 by the reaction force acting from the main guide member 31. It becomes easy to be displaced in the lifting direction.

  On the other hand, as in another embodiment (a), by forming the contact portion 25b on the regulating member 25, a force acting in a direction for displacing the main guide member 31 upward is applied via the regulating member 25. By transmitting the displacement to the case 10, the displacement is received by the regulating member 25 and the case 10, and the substrate 1 can be more reliably held at an appropriate position.

  In this alternative embodiment (a), as the contact portion 25b, a plate-like structure in which the plate thickness becomes smaller toward the upper end is shown, but instead of this configuration, the contact portion 25b becomes flat along the inner surface of the upper wall 11. A contact structure may be used.

(B) As shown in FIGS. 10 and 11, the contact portion 24 b that contacts the inner surface of the lower wall 12 of the case 10 is arranged on the opposite side of the pressing portion 24 a with respect to the pressing member 24 (an example of the pressing holding portion H). Form. That is, when the cover 20 is in the position to close the opening 10 a of the case 10, the pressing portion 24 a of the pressing member 24 contacts the lower surface of the substrate 1 and the contact portion 24 b of the pressing member 24 It is constituted so that it may contact the inner surface of.

  The pressing member 24 functions to press the lower surface of the substrate 1 to apply a pressure. However, the pressing member 24 is easily displaced downward from the substrate 1 by a reaction force applied from the substrate 1.

  On the other hand, by forming the contact portion 24b of the pressing member 24 as in another embodiment (b), a force for displacing the pressing member 24 downward is transmitted to the case 10 via the pressing member 24. Accordingly, the displacement can be received by the pressing member 24 and the case 10, and the force acting on the substrate 1 from the pressing member 24 can be reliably maintained.

  In this alternative embodiment (b), as the contact portion 24b, a plate-like structure in which the plate thickness becomes smaller toward the lower end is shown, but instead of this configuration, the contact portion 24b becomes flat along the inner surface of the lower wall 12. A structure may be used.

  Note that the housing A may be configured to include one of the configuration of the regulating member 25 of another embodiment (a) and the pressing member 24 of another embodiment (b). As shown in FIG. 11, the housing A may be configured to include both the configuration of the pressing member 24 of another embodiment (a) and the configuration of the regulating member 25 of another embodiment (b).

  Further, in the configuration having only the pressing member 24 of another embodiment (b), it is preferable to increase the vertical length (width) of the main guide member 31 to increase the rigidity of the main guide member 31. Accordingly, even when the substrate 1 is pressed against the main guide member 31 by the pressing member 24, the main guide member 31 is hardly deformed, and the substrate 1 can be held at an appropriate position without the regulating member 25.

(C) As shown in FIG. 12, the main guide member 31 is formed so as to extend inward from the side wall 13 and to project further inward (to the right in FIG. 12) than the sub guide member 32, and the direction shown in FIG. When viewed, the pressing member 24 is pressed against the bottom surface of the substrate 1 at a position not overlapping with the sub guide member 32, and the regulating member 25 is disposed above the pressing member 24.

  In the configuration of this other embodiment (c), the pressing member 24 can be arranged at a position that does not overlap with the sub-guide member 32 when viewed in the direction shown in FIG. 12, so that the sub-guide member 32 reaches the vicinity of the opening 10 a of the case 10. Can be easily set in the guide path between the main guide member 31 and the sub guide member 32 when the substrate 1 is accommodated in the case 10. Becomes

(D) As shown in FIG. 13, in a state where the substrate 1 is accommodated in the case 10, the lower end of the pressing member 24 provided on the cover 20 is brought into contact with the upper surface of the substrate 1, and the upper end of the pressing member 24. The contact portion 24b is configured to contact the inner surface of the upper wall 11 of the case 10.

  In this alternative embodiment (d), the pressing and holding portion H is constituted by the pressing member 24 and the sub-guide member 32. In this configuration, in a state where the cover 20 is provided at a position where the opening 10 a of the case 10 is closed, the contact portion 24 b of the pressing member 24 contacts the inner surface of the upper wall 11 of the case 10, and the lower surface of the substrate 1 It contacts the sub guide surface 32a.

  Further, in this alternative embodiment (d), when the substrate 1 is inserted into the case 10, the projection 33 that comes into contact with the upper surface of the distal end in the insertion direction of the substrate 1 is provided to project downward from the main guide member 31. . As in the embodiment described above, the distance between the protruding end of the protrusion 33 and the sub guide surface 32a is set slightly smaller than the thickness of the substrate 1, and the plate thickness is set smaller for the protruding end. . Further, the thickness of the pressing portion 24a of the pressing member 24 is set to be smaller at the protruding end.

  In this alternative embodiment (d), although the length in the guide direction is set so that the sub guide member 32 reaches the vicinity of the opening 10a from the bottom wall 14, the main guide member 31 is different from the sub guide member 32. In comparison, it is formed in a shape excluding a portion near the opening 10a. Accordingly, when the cover 20 is provided at a position where the opening 10 a of the case 10 is closed, the pressing portion 24 a on the lower surface of the pressing member 24 is disposed in a space formed on the outer end side of the main guide member 31.

  In this configuration, since the sub-guide member 32 is formed at a position in contact with the lower wall 12, a member corresponding to the regulating member 25 described in the embodiment becomes unnecessary, and the pressing force of the pressing member 24 is reduced to the upper surface of the substrate 1. , The substrate 1 is brought into strong contact with the sub-guide surface 32a of the sub-guide member 32, and the substrate 1 can be supported without causing the substrate 1 to vibrate.

  INDUSTRIAL APPLICATION This invention can be utilized for the housing | casing which accommodates a board | substrate.
